Enhancing barocaloric effects in molecular crystals by electric field
Cooling technologies based on caloric effects in solids driven by external fields are currently being proposed as environmentally friendly and efficient alternatives to gas compression refrigeration. Recent experiments carried out by our group of barocaloric effects driven by hydrostatic pressure have revealed that the molecular crystal [C6H7N2]+.BF4- (dabcoHBF4) possesses extraordinary barocaloric properties. The ferroelectric transition underlying these colossal barocaloric effects suggests that the application of electric field may also entail excellent electrocaloric performance. Neutron diffraction experiments can provide key information about the fascinating possibility to drive multicaloric effects in dabcoHBF4.
